Toxic Agent Flow – Accessing private repositories via MCP
As AI coding assistants become indispensable—automating repetitive tasks, surfacing code suggestions, and even drafting entire functions—their seamless integration into our workflow can lull us into a false sense of safety. In this article, we’ll explore how a seemingly harmless issue on GitHub can trigger what security researchers call a “Toxic Agent Flow,” leading to the exfiltration of private data. We’ll then examine concrete steps you can take today to lock down your environment and evolve your security model for an AI-driven world.
